Most rising countries have poor regions deprived from electricity. For such citizens, a small portion of electricity can promote life-enhancing changes in all spheres. They require a new and sustainable approach to solve this problem.
Solar power can be one of these solutions. Citizens can utilize solar energy to use for their parks and street lights and warm their water for almost free maintenance after setting up. Amongst those solar items, solar boulevard lights may become a specific concern for the program that can be sponsored by the government and then be effective for many people. For instance, the bigger part of African continent has about 300 days of intensive sunlight a year and it can generate more than 6 kilowatt of energy per hour.
As for technological issues, there are two ways of utilizing solar power: thermal method to accumulate the heat of the sun and photovoltaic method to convert the sun’s light into electricity. Latest ways of usage is a combination of mirrors and lenses to focus a large area of sunlight into a small ray and can produce enough heat. The last utilizes photoemissive element to transform the energy of the sun into electricity, which is utilized from a solar-powered lamp to a big solar power station.
Solar power can be accessed in two ways: purchasing in the open market and taking international aid. Compute the price for a simple solar photovoltaic system. About 90% of photovoltaic methods have silicon basis. The solar energy system should be connected to the electricity grid with the help of a tool called an inverter. The system also demands batteries to save surplus energy. Moreover, an electric charge regulator should save the batteries from overheating. All these vital parts are rather expensive.
So, the cost of making and installing solar energy system is a major problem for such poor states. In the case of poor countries, now they should develop the solar power systems through international charity organizations. A wide range of models is being utilized now. Companies and some funders such as World Bank and the International Finance Corporation maintain solar projects in Africa, Latin America and Asia. Those aid projects are lead to enhance health, education and quality of life.
However, with development of technological advancements, more and more financial investments are being put into solar field. During the past five years, the total amount of investments in solar projects made 33 billion of dollars in 2008, it grew to 172% as compared to data of 2004.
Besides economical facts, there are other hindrances for the mass utilization of solar power for the poor areas. The policy environment supporting fossil fuels is one of these problems, although every government declares to reduce global emissions. Other difficulties include improving local ownership of solar power technologies.
Practically any charity funds look for new ideas for charity fundraising . The Internet has changed into a new charity fundraising way. It is not that difficult to create a charity fundraising website but its output is great.
